The gentle strains of Fleetwood Mac's 'Landslide' provided the soundtrack to a surprisingly melancholy montage on last night's 'South Park' season finale. It was truly touching, as any scene filled with multiple visions of floating poop can possibly be.

The lyrics to the tender ballad, from the band's self-titled 1975 album, tie in perfectly with the major plot development revealed during the episode. We don't want to trade in spoilers, but as you'll see if you watch the video below, it looks like one of the main four 'South Park' kids is moving away.

Once you know that, it's clear that Stevie Nicks' ruminations about growing and changing aren't being used as a punchline: "Well, I've been afraid of changing / Because I built my life around you / But time makes you bolder / Children get older / I'm getting older, too."

So, are they really going to shake up the status quo so much in this, the popular and sometimes controversial animated show's 15th season? It's possible; but then again, they've killed Kenny about three hundred times so far, only to have him come back the next day, so maybe next season this all blows over and everybody's back together.

Of course, earlier this season, 'South Park' blew the lid off one of the biggest secrets in rock n' roll, stating that former Guns N' Roses guitarist Slash doesn't actually exist.

As for Nicks, she recently released a brand new solo album, 'In Your Dreams.' You can read our review of the first single 'Secret Love' and, as a treat, listen to the song at the very same time. Reportedly, Fleetwood Mac will hit the road for another world tour sometime in 2012.
